Isn't a refractometer only effective for getting OG? The Beer Bug is designed to monitor constantly during fermentation.

You can use a refract to get FG you just need to apply some correction factors to the reading. This is because, If I recall, the refractive index of sugar and alcahol are similar so the refractometer can't distinguish when alcahol and sugare are both present.

It has nothing to do with how similar they are, it is just that they are both non-zero.
